During the ignition and operation of the chamber combustion boiler fueled by pulverized coal, oil or combustible gas, improper operation can cause the deflagration or secondary combustion in the furnace or flue gas duct, which can further cause the increased pressure in the furnace. When the pressure reaches a certain value, the explosion-proof door is necessary to open automatically to protect the furnace wall of the boiler.
Regular maintenance is essential to ensure safe and efficient operation of industrial thermal oil heaters. Here are some of the key maintenance tasks that should be performed:
1. Daily checks: The operator should perform daily checks of the heater, including checking the fuel level, the temperature of the thermal oil, and the pressure of the system.
2. Cleaning: The heater should be cleaned regularly to remove any buildup of soot, ash, or other debris that can reduce efficiency or cause damage...
The main purpose of boiler acid washing is to remove iron oxide, copper scale, iron scale and other impurities in the evaporation heating surface of the boiler, and also to eliminate silicon dioxide and scale.
First, let's explain what an industrial oil-fired boiler is. The industrial oil-fired boilers refer to boilers that use oil as the fuel. Generally, they burn diesel oil, special fuel oil for boilers, heavy oil and waste oil, etc. However, due to the rising price of diesel oil and the problem of supply, they are now turning to fuel oil.
A steam boiler is a water containing vessel which transfers heat generated by a fuel source into steam, which is then piped and directed to points where it could be used while running industrial equipment. The basic idea here is to convert water to steam using a source of heat.
Gas-fired industrial boilers are high-efficiency, eco-friendly and energy-saving, and they play an important role in the production-oriented enterprises. Due to strict requirements for pollutant emissions, enterprises often attach great importance to the emission performance of boilers.
Combustion efficiency is an indication of the burner’s ability to burn fuel. The amount of unburned fuel and excess air in the exhaust are used to assess a burner’s combustion efficiency. Burners resulting in low levels of unburned fuel while operating at low excess air levels are considered efficient. Well designed conventional burners firing gaseous and liquid fuels operate at excess air levels of 15% and result in negligible unburned fuel. Well designed ultra low emissions burners operate at a higher excess air level of 25% in order to reduce emissions to very low levels. By operating at the minimum excess air requirement, less heat from the combustion process is being used to heat excess combustion air, which increases the energy available for the load. Combustion efficiency is not the same for all fuels and, generally, gaseous and liquid fuels burn more efficiently than solid fuels.
ASME code – also known by its longer name: ASME Boiler & Pressure Vessel Code – regulates the design, development, and manufacturing of boilers used in a variety of industries and applications.
This code was developed by the American Society of Mechanical Engineers, an organization that has been around for well over 100 years and is focused on establishing safety codes and standards for mechanical equipment.
Within the industrial heating industry, ASME code is the established standard that many pieces of equipment are built to.
Heating systems that adhere to the specifications set forth by ASME code have been constructed according to guidelines intended to promote safety and quality. As such, heating equipment that is ASME code compliant has been thoroughly inspected to assure that it meets high safety and quality standards.
